Actually, it looks like there is something in the law that only provides DMCA safe harbor to providers that have a policy of terminating accounts of repeat infringers. I'm still not sure if an ISP would even need that safe harbor though.
I don’t think so. They need to have the policy of terminating accounts and actually terminate a subset of them. They just can’t be held liable for not terminating all of them.
This was what GFiber appeared to be doing until it sold out to private equity. I got about 60 DMCA notice emails about torrents that never reached seeding state. About 25% of them were false accusations with wrong titles unrelated to activity by anyone on my network.
